실험 절차
2,1 g of cis-6-(4-aminophenyl)-8,9-dimethoxy-2-methyl-1,2,3,4,4a,10b-hexahydro-benzo[c][1,6] naphthyridine are heated to 100° for 21/2 hours in 50 ml of 90% formic acid. The reaction solution is evaporated to dryness in a vacuum, the resulting residue is made alkaline with a dilute potash solution and this aqueous phase is extracted with methylene chloride. After drying and concentrating the organic phase by evaporation, the title compound is obtained as a yellow oil and crystallizes after the addition of ethanol in the form of yellowish prisms having a melting point of 140°-145°.
